A New Plasticizer Of Comprehensive Action On The Basis Of Sugar Industry Waste

[摘要] The effect of a new plasticizing additive to construction cement concrete is studied. Its main component is molasses, which is a waste of beet sugar production. To regulate the mobility and strength of the concrete mixture, the rate of its setting and hardening, surfactants and compounds of alkali and transition metals were additionally introduced into the molasses. It is shown that the optimal variant of the additive in terms of mobility and strength of the concrete mixture exceeds the known commercial plasticizer PFM-NLK. The new additive, unlike PFM-NLK, allows to use sand of various fractional and mineralogical composition in the production of concrete. The possible influence of physical and chemical parameters and chemical composition of molasses on the characteristics of cement concrete is discussed.
